A recent study suggests that vast reserves of white hydrogen, a clean and renewable fuel, may be hidden within mountain ranges. Scientists are focusing on the potential of white hydrogen to replace fossil fuels and combat the climate crisis. White hydrogen, also known as natural or geologic hydrogen, has sparked interest due to its environmentally friendly characteristics. The study uses computer models to locate regions, such as the Pyrenees and European Alps, where conditions are favorable for white hydrogen generation through processes like 'serpentization.' This natural gas could revolutionize energy production in industries like aviation and steel-making. While the commercialization process may be lengthy, ongoing exploration in countries like France, the Balkans, and the US aims to unlock the vast potential of white hydrogen. The discovery of white hydrogen highlights a promising pathway towards a sustainable and cleaner energy future.
